Endemic coastal malaria in the Thousand Islands District, near Jakarta, Indonesia.

Objectives: To conduct malaria surveillance near Jakarta where only imported malaria has been described over the past two decades and to characterize endemicity and risk to heavily populated peri-urban locations.

Methods: Standard cross-sectional malariometric surveys and mosquito collections at the Thousand Islands District and developing peri-urban areas of Jakarta.

Results: During October 2000 outbreak investigations in the Tidung Island group, the slide positive rate was 47% (38%Plasmodium falciparum, 7%P.

Chloroquine or sulfadoxine-pyrimethamine for the treatment of uncomplicated, Plasmodium falciparum malaria during an epidemic in Central Java, Indonesia.

A recent malaria epidemic in the Menoreh Hills of Central Java has increased concern about the re-emergence of endemic malaria on Java, which threatens the island's 120 million residents. A 28-day, in-vivo test of the efficacy of treatment of malaria with antimalarial drugs was conducted among 167 villagers in the Menoreh Hills. The treatments investigated, chloroquine (CQ) and sulfadoxine-pyrimethamine (SP), constitute, respectively, the first- and second-line treatments for uncomplicated malaria in Indonesia.

The drug sensitivity and transmission dynamics of human malaria on Nias Island, North Sumatra, Indonesia.

Nias Island, off the north-western coast of Sumatra, Indonesia, was one of the first locations in which chloroquine-resistant Plasmodium vivax malaria was reported. This resistance is of particular concern because its ancient megalithic culture and the outstanding surfing conditions make the island a popular tourist destination. International travel to and from the island could rapidly spread chloroquine-resistant strains of P.

Chloroquine-resistant Plasmodium malariae in south Sumatra, Indonesia.

Oral chloroquine is the treatment of choice for uncomplicated Plasmodium malariae infections worldwide. We did a prospective 28-day in-vivo assessment of the efficacy of chloroquine for treatment of P malariae on Legundi Island in Lampung Bay, Sumatra, Indonesia. Of 28 patients, one had recurrent parasitaemia on day 28, and two had persistent parasitaemia to day 8.

Humoral immune responses against Plasmodium vivax MSP1 in humans living in a malaria endemic area in Flores, Indonesia.

The aim of this study was to evaluate the relationship among age, parasitemia status, spleen size, hematocrit, and antibody levels to Plasmodium vivax merozoite surface protein 1 (MSP1) in individuals chronically exposed to P. vivax. Subjects were recruited from the population of three adjacent villages on the Island of Flores in Indonesia where malaria transmission is hyperendemic and tropical splenomegaly syndrome is highly prevalent.
